Computer Science AS/A2 Level at Christleton High School

Course description


Computing considers how computers work and how they process data and information.

Students who study Computing will enjoy logic and problem solving. They will be interested in how computers process data and information, how calculations are carried out and how data is transmitted.

Topics to be covered include writing psuedocode and algorithms, binary number systems, stages of development in a software system, logic gates, big data, internal components of a computer, the structure of the Internet and networking protocols.

In programming, students will enjoy finding solutions to problems such as how to add 2 numbers together; how to build a form based interface for a quiz program or how to make a space rocket move up the screen!

All of this will be considered in the light of current social, ethical and moral issues.

Course content


The AS course consists of 2 units which includes a practical paper examined on screen where students are expected to write, adapt and fix code given to them from the board in the form of pre-release material. There is also a written paper covering some of the topics mentioned above.

The Advanced Level course covers additional topics in the 2 papers mentioned above and also requires students to complete a piece of coursework which is worth 20% of the final grade.

Entry requirements


5 GCSEs A*-C including Grade C in English and B in Maths.


2 Exams and Coursework.

Future opportunities


Students who study computing may go on to University to study the subject at degree level, but A level Computing is not a requirement for this. The subject develops good problem solving and logical thinking skills which can be applied to many different subject areas.
